Effects of intrauterine and cervical artificial-insemination catheters on farrowing rate and litter size
Materials and methods: Three hundred eighty-nine sows were allotted into two experimental groups by parity, body condition score, and breed-of-sire influence. Sow matings were performed using a disposable foam-tipped intrauterine catheter (IU, n = 193) or a cervical catheter (IC, n = 196). Total number of piglets born per litter was recorded, and farrowing rates were calculated after all sows h...
متن کاملIntrauterine artificial insemination of swine with different sperm concentrations, parities, and methods for prediction of ovulation
This study compared the reproductive performance of sows that were submitted to cervical artificial insemination (CAI) using concentrations of 3.5 x 10 spermatozoa per dose or intrauterine artificial insemination (IUAI) with 2, 1, or 0.5 x 10 spermatozoa per dose. Within all treatments, females were inseminated either after conventional estrus detection or after ultrasound-guided ovulation diag...
متن کاملSperm Concentration on the Intrauterine Artificial Insemination in Swine
The aim of this work was to evaluate the efficiency of the intrauterine insemination (IUI) in swine, considering the conception rate, farrowing rate, litter size (alive born pigs). For the IUI, the females had been insemination at 24 and 48 hours after the estrus detection, and the inseminating doses of 500 million, 1 billion, 1.5 billion and 2 billion spermatozoa in 20 mL extender had been use...
متن کاملConception Rate, Farrowing Rate and Litter Size after Intrauterine Insemination with Cryopreserved Boar Semen in Spontaneous and Induced Ovulation Sows
Introduction The procedure for artificial insemination (AI) in pigs using cryopreserved semen involves the deposition of a high number of cryopreserved spermatozoa (5-6 x10 cells) in a large volume of diluent (80-100 ml) into the cervix. Despite inseminating with this high sperm number, low fertility levels are usually obtained (about 20-30% conception and farrowing rates and 2-3 total piglets ...
متن کاملConception Rate and Litter Size in Multiparous Sows after Intrauterine Insemination Using Frozen-Thawed Boar Semen in a Commercial Swine Herd in Thailand
The aim of the present study was to determine the conception rate and litter size in sows after fixed time intra-uterine insemination using frozen-thawed boar semen in a commercial swine herd in Thailand. Sixty-nine Landrace multiparous sows were randomly allocated into two groups, including control (n=36) and treatment (n=33). The control sows were inseminated with extended fresh semen (3 × 10...
